Thanks for the great info, I,m watching this post closely, as I to have alot tail weight and it drops the tail when I slow down. I too question the CG as written, and nobody until now confirmed that it is possible that " THIS BATCH" of F-16,s Is different , flies different and as built, tail heavy at 8.5 - 9 inches. I will now drop half my ballest weight. I dead sticked mine into a young corn field with repairable damage to one main retrack mount plate. gear down 8 and 3/8,s cg last flite. Going to aprox 8 inchs next flight and lower if needed after that.
